damage to property. The notices referring to your personal safety are highlighted in the manual by a safety
alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown
below are graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger
will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning
relating to property damage.

Introduction
1.4Cabling Recommendations
1.4 Cabling Recommendations
All copper Ethernet ports on RUGGEDCOM products include transient suppression
circuitry to protect against damage from electrical transients and conform with
IEC 61850-3 and IEEE 1613 Class 1 standards. This means that during a transient
electrical event, communications errors or interruptions may occur, but recovery is
automatic.
Siemens does not recommend using copper Ethernet ports to interface with devices
in the field across distances that could produce high levels of ground potential rise
(i.e. greater than 2500 V), during line-to-ground fault conditions.
1.5 High Availability Seamless Ring Operation
Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR)
are two mechanisms defined by the IEC 62439-3 standard to provide hitless network
recovery. Unlike Spanning Tree Protocol (STP), which requires reconfiguration of the
active network topology over redundant physical links, HSR and PRP provide hitless
network recovery through the use of information replication.
1.5.1 Parallel Redundancy Protocol
Parallel Redundancy Protocol (PRP) provides hitless network recovery by replicating
information over two physically independent Ethernet networks. The following
illustrates a typical PRP network:

Figure1.2 PRP Network Design
Note
PRP expands the Ethernet frame by 6 octets due to RCT (Redundancy Check Trailer).
Generation of PRP supervision frames also consumes bandwidth. As a result, the
network designer should keep in mind the overhead introduced by the PRP network
when calculating the network capacity.
1.5.2 High Availability Seamless Redundancy
The basic principle behind High-availability Seamless Redundancy (HSR) is the
replication of frames over both sides of the HRS ring. The following illustrates a
typical HSR network:

Figure1.3 HSR Network Design
All of the network nodes inside an HSR ring must be HSR-capable. HSR-unaware
nodes can be attached to the HSR ring through the use of a RedBox (Redundancy
Box). Compared to PRP, HSR only demands approximately half of the network
infrastructure. However, network bandwidth on an HSR ring is approximately halved
compared with a network ring based on RSTP technology.

Installing the Device 2
This section describes how to install the device, including mounting the device,
connecting power, and connecting the device to the network.
DANGER
Electrocution hazard – risk of serious personal injury and/or damage to
equipment
Before performing any maintenance tasks, make sure all power to the device has
been disconnected and wait approximately two minutes for any remaining energy
to dissipate.
WARNING
Radiation hazard – risk of serious personal injury
This product contains a laser system and is classified as a CLASS 1 LASER PRODUCT.
Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
IMPORTANT
This product contains no user-serviceable parts. Attempted service by unauthorized
personnel shall render all warranties null and void.
Changes or modifications not expressly approved by Siemens AG could invalidate
specifications, test results, and agency approvals, and void the user's authority to
operate the equipment.
IMPORTANT
This product should be installed in a restricted access location where access can only
be gained by authorized personnel who have been informed of the restrictions and
any precautions that must be taken. Access must only be possible through the use
of a tool, lock and key, or other means of security, and controlled by the authority
responsible for the location.
2.1 Mounting the Device
The RUGGEDCOM RS950G is designed for maximum mounting and display flexibility.
It can be equipped with connectors that allow it to be installed in a 35 mm (1.4 in)
DIN rail or directly on a panel.

Installation Manual, 01/2021, C79000-G8976-1037-06 7

Installing the Device
2.1.1Mounting the Device on a DIN Rail
Note
For detailed dimensions of the device with either DIN rail or panel hardware installed,
refer to "Dimension Drawings (Page 23)".
2.1.1 Mounting the Device on a DIN Rail
For DIN rail installations, the RUGGEDCOM RS950G can be ordered with a DIN rail
mounting bracket pre-installed on the rear of the chassis. The bracket allow the
device to be slid onto a standard 35 mm (1.4 in) DIN rail.
IMPORTANT
DIN rail mounting is not recommended for constant vibration environments.
To mount the device to a DIN rail, do the following:
1. Pull the DIN rail adapter down and clip the device on to the DIN rail. Release the
adapter to secure the device.

2.1.2 Mounting the Device to a Panel
For panel installations, the RUGGEDCOM RS950G can be ordered with mounting
brackets that mount to the top and bottom of the chassis.
To mount the device to a panel, do the following:
1. Remove the bracket mounting screws from the top and bottom of the chassis.

4. Using #6 screws of sufficient length (not provided), secure the mounting
brackets to the panel. Use wall anchors (not provided) where required.
2.2 Connecting the Failsafe Alarm Relay
The failsafe relay can be configured to latch based on alarm conditions. The NO
(Normally Open) contact is closed when the unit is powered and there are no active
alarms. If the device is not powered or if an active alarm is configured, the relay
opens the NO contact and closes the NC (Normally Closed) contact.
Note
Control of the failsafe relay output is configurable through RUGGEDCOM RS950G .
One common application for this relay is to signal an alarm if a power failure
occurs. For more information, refer to the RUGGEDCOM RS950G User Guide for the
RUGGEDCOM RS950G.

2.3 Connecting Power
The RUGGEDCOM RS950G supports a single integrated high AC/DC or low DC power
supply
IMPORTANT
• For 110/230 VAC rated equipment, an appropriately rated AC circuit breaker
must be installed.
• For 125/250 VDC rated equipment, an appropriately rated DC circuit breaker
must be installed.
• Use minimum #16 gage wiring when connecting terminal blocks.
• Equipment must be installed according to applicable local wiring codes and
standards.
• All line-to-ground transient energy is shunted to the Surge Ground terminal. In
cases where users require the inputs to be isolated from ground, remove the
ground braid between Surge and Chassis Ground. Note that all line-to-ground
transient protection circuitry will be disabled.
IMPORTANT
Siemens requires the use of external surge protection in VDSL applications where
the line may be subject to surges greater than that for which the device is rated. Use
the following specifications as a guide for VDSL external surge protection:
• Clamping Voltage: 50 V to 200 V
• Insertion Loss: < 0.1 dB at 10 MHz
• Peak Surge Current: 10 kA, 8x20µs waveform
